nae bother mate, always welcome these questions
The cambelt is due every 90k or 5/6 years iirc, only one on the 4 pot K so that shouldn't be too bad cost wise.
Check for signs of HGF, or if it has been done already what else was done at the same time as they won't just go by themselves.
check all controls on the dash work tickety boo.
check fuel tank as they cut back on underseal from about 04 on and although it isn't usually that bad if someone has done the fuel tank themselves all the better.
check horn and alarm works, that all doors lock off the fob.
check condition of seats- excess wear or the bottom squab making an escape from the seat itself.
There was a recall to stop windows going down when intermittant wiper was on find out if this has been done if not it is an easy fix anyhoo
Check exhaust- should be a new one round about this age or check old one isn't for the off.
Thats most of what i can think of right now, hope it helps
